[Buildroot] [PATCH v3] imx6q-sabresd: Add a qt5 defconfig variant

[Fabio Estevam]

Introduce imx6q-sabresd_qt5_defconfig that supports the opensource
Etnaviv graphical stack.

This defconfig provides a way to quickly test some graphical applications,
such as kmscube, qt5, glmark2.

Currently kernel mainline exhibits issues when running cpufreq as ondemand
governor on mx6, so add a linux fragment that disables such option for the
time being.

Changes since v2:
- Drop BR2_PACKAGE_MESA3D_DRI_DRIVER_SWRAST (Thomas)
- Bump to the latest kernel 4.11.6

Ping, I have been trying to submit this patch for months, but no
progress so far.

 Hi Fabio, I applied to next, with a lot of changes:

     - Add Fabio to DEVELOPERS
     - Rename linux config fragment to linux_qt5.fragment
     - Add comment to linux_qt5.fragment why it is needed
     - Add explicit CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y to it
     - Reorder defconfig entries to they match imx6q-sabresd_defconfig
     - Remove strace and host-uboot-tools, neither seems to be needed
     - Drop BR2_PACKAGE_QT5BASE_LICENSE_APPROVED, it no longer exists
     - Replace BR2_TARGET_ROOTFS_EXT2_BLOCKS with BR2_TARGET_ROOTFS_EXT2_SIZE
     - Regenerate .gitlab-ci.yml

 Could you re-test based on the next branch?

 Also, you set BR2_TOOLCHAIN_BUILDROOT_GLIBC=y but none of the packages selected
seem to need it. Is there a reason why it is needed? Could you either remove it
(after testing with uClibc-ng) or add a comment why it is needed and remove
BR2_TOOLCHAIN_BUILDROOT_WCHAR=y?

 Regards,
 Arnout

Thanks for reworking the patch and applying it.

I am currently out of the office without hardware access to test it.

Will test it as soon as I am back to the office (week of August 21)

Sure, will do it.

Thanks

I was able to test it and can confirm that it works as expected.

I tried the following change:

--- a/configs/imx6q-sabresd_qt5_defconfig
+++ b/configs/imx6q-sabresd_qt5_defconfig
@@ -8,9 +8,7 @@ BR2_ARM_FPU_VFPV3=y
 BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_4_11=y

 # Additional features needed for packages
-BR2_TOOLCHAIN_BUILDROOT_WCHAR=y
 BR2_TOOLCHAIN_BUILDROOT_CXX=y
-BR2_TOOLCHAIN_BUILDROOT_GLIBC=y

 # System

,but in this case the Qt5 package is not installed anymore.

Ok, this is expected as Qt5 depends on BR2_TOOLCHAIN_BUILDROOT_WCHAR.

So I will only remove BR2_TOOLCHAIN_BUILDROOT_GLIBC=y from the defconfig.

Let me test it and will send a patch if it works.
